Physics of a Fall
• A body in motion (free fall) can cover vast
  distances in a short period of time. Consider
  this:
  – A body in free fall can travel 4 ft in 0.5 seconds
  – A body in free fall can travel 16 ft. in 1 second
  – A body in free fall can travel 64 ft. in 2 seconds
Application of Regulations
• Subpart M (1926.500) applies to fall
  protection during construction activities.
• There are a few exceptions from this rule
  for the following activities:
  – Inspection
  – Investigation
  – Assessing conditions prior to or after the work
    is performed
Application of Regulations
• Other existing standards for fall protection
  are discussed in different standards (subpart
  M would not cover the following items):
  –   Scaffolds (subpart L)
  –   Cranes (subpart N)
  –   Steel Erection (subpart R)
  –   Stairs and Ladders (subpart X)

  absorbing.
Types of Lanyards
• Self retracting
   – Eliminates excess slack in the lanyard (cable, rope, or
     web)
• Shock absorbing
   – Device slows and eventually stops decent and absorbs
     the forces (i.e.: rip stitch controlled tearing)
• Synthetic rope
   – Absorbs some of the force by stretching
• Synthetic webbing

PFAS (life Lines) 1926.502(d)
• Life lines consist of flexible material connected at
  one or both ends to an anchorage point.
• There are two types of life lines:
   – Vertical:hangs vertically (5000 pound minimum
     breaking strength)
   – Horizontal: connects at both points to stretch
     horizontally (serves as connection point for other
     components of PFAS-total system must have safety
     factor of two).
PFAS (Snap hooks) 1926.502(d)

  it is above the employee’s head. Located as
  to not allow an employee fall more than 6
  feet.
• All anchorage points must be a solid
  immovable object that is capable of
  supporting 5000 pounds.
• Must not be used to support anything else.
Positioning Device Systems

• Allows employee to be supported from a vertical
  surface (i.e.: wall or telephone pole).
• Must be inspected before each use for defects.
• Must be rigid for no more than a 2 foot free fall.
• Not a fall arrest system!
• The anchorage point must be capable of
  withstanding twice the potential impact of an
  employee’s fall or 3000 pounds, whichever is
  greater.
Warning Line System

  (strength of 200 pounds) erected 10-15 feet
  from the edge
• Lines must be flagged at six foot intervals.
Safety Monitoring System
            1926.502(h)
• Uses a monitor (competent person) to patrol
  the area and warn employees of the
  dangers.
• All safety monitors must comply with the
  following criteria:
